Abstract：Objective To investigate the clinical outcomes of posterior circular decompression to treat thoracic disk herniation combined with ossification. Methods Twenty-five patients who had thoracic disk herniation combined with ossification underwent the procedure of posterior circular decompression. The lesion segment was T4/5、T5/6 in 2 cases, T6/7 in 1case, T8/9 in 2 cases, T9/10 in 4 cases, T10/11 in 6 cases and T11/12 in 8 cases. The postoperative curative effect was measured by JOA score and Otani scoring system. Results The average operative time was (175.7±12.4) min with a mean blood loss was (630.8±33.7) ml. Five patients exhibited intraoperative cerebrospinal fluid leakage, and recovered after treatment. One case developed wound hematoma and recovered after an emergency debridement. Compared with the preoperative level (6.3±2.1), the JOA score had a significant recovery at 3 months (9.4±3.0) and at the last follow-up (9.7±3.3)(P＜0.05). The Otani score at the last follow-up was excellent in 13 patients, good in 8 patients, fair in 3 patients, and poor in 1 patient, and the good response rate was 84.0%. Conclusions The posterior circular decompression in treating thoracic disk herniation combined with ossification can obtain good clinical results. However, attention should be paid to avoid cerebrospinal fluid leakage.
